The information below was adapted from OpenStax Biology 30.2. Stems are the part of the plant, that possesses buds, leaves and roots at its basal ends. It supports and holds leaves, flowers and fruits. Their main function is to provide support to the plant, holding leaves, flowers and buds; in some cases, stems also store food for the plant. Stems are usually above ground, although the stems of some plants, such as the potato, also grow underground. 3. If you saw cross sections of Begonia or Coleus and alfalfa stems side by side, what differences would be obvious? Development; Root: The development of the root begins from the primary root in the embryo, called radicle. Their main function is to provide support to the plant, holding leaves, flowers and buds; in some cases, stems also store food for the plant. Secondary Growth: Secondary growth is the growth that occurs by the action of … Stems support leaves (the "hat racks" upon which plants hang their solar collecting leaves). Stems may be herbaceous (soft) or woody in nature. Dicot stems with primary growth have pith in the center, with vascular bundles forming a distinct ring visible when the stem is viewed in cross section. Xylene, balsam. Plants that undergo only primary growth and have soft, green, non-woody stems are known as herbaceous plants. Perform most of the metabolic function so the plant. Stems are often specialized for storage, asexual reproduction, protection or photosynthesis, including the following: Bulb - a short vertical underground stem with fleshy storage leaves attached, e.g. What is the primary function of stems a. Facilitation of gas exchange b. Biology. Jamal was cutting the grass and started sneezing because of the pollen. Modified stems that grow horizontally underground are either rhizomes, from which vertical shoots grow, or fleshier, food-storing corms.

One of the main functions of a stem is to pass water and dissolved minerals from the roots to the leaves. Related Questions in Biology. The primary function of leaves is to collect sunlight and make food by photosynthesis. Absorption of Water: Roots absorb water from soil. The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transpor t these products from the leaves to other parts of the plant, including the roots. However, stems are fundamental to plants and superbly adapted to the role they play. Roots While roots are most often found underground, this is not universally the case. Subsequent cell elongation then leads to primary growth. The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species.
